Mechanical development of looms

The loom, the common name of the loom. The earliest loom, is seated on the floor of the coiled loom (also called waist machine). The method of use is to step on the loom with a foot warp stick, the right hand holding the weft knife in the tightening of the weft, the left hand in the gesture of casting the weft lead. This foot stomping waist machine without a frame, one end of the rolled cloth shaft tied to the waist, feet stomping on the other end of the warp and tension fabric, with the warp stick will be divided into two layers of warp yarn according to the number of odd and even, with the heddle rod to lift the warp to form the mouth of the shuttle, to the bone needle to lead the weft, the weft knife to beat the weft. The most important achievement of waist loom weaving is the adoption of the heald lifting rod, warp splitting stick and weft knives. Although this loom is very simple, it already has 3-direction movement such as opening the weaving mouth up and down, leading the weft left and right, and tightening the weft front and back, and it is the ancestor of the modern loom.

People in the production practice of weaving, and gradually innovated and successfully created a foot pedal to mention the oblique loom. Its image, in the Han Dynasty portrait stone appeared many times. This oblique loom already has a frame, the warp surface and the horizontal seat into fifty or sixty degrees of inclination, and the use of the feet to lift the opening of the device. Weaving people can sit and operate, hands and feet, productivity than the original loom is generally increased by more than 10 times, is the world's most advanced loom at that time.

In the development of the modern textile industry, a variety of forms of shuttleless loom, rapier loom, piece shuttle loom, air-jet loom, water jet loom, multi-phase loom, magnetic weft loom and so on. Compared with shuttle loom, shuttleless loom production of fabrics in terms of yield, quality, variety and so on have unparalleled advantages in most of the weaving field to replace the shuttle loom, the pace of this further accelerated, has been from the textile industry in the developed countries to expand to developing countries. From the international shuttleless loom technology development and textile industry demand, air jet loom high-speed, wide, series of faster progress, in addition to the large number of widely used in the cotton industry, in the color, jacquard and other fabrics are increasingly wide range of applications, and rapier loom varieties of adaptability, changes in the fabric varieties of color, weaving a wider range of aspects such as the advantages of the two types of looms to become the textile industry, the application of the largest number of two types of models. The two types of looms have become the most used in the textile industry.
